Why Do Windshield Wipers Make Noise?
2 Answers
Windshield wipers make noise due to the following reasons: 1. Foreign objects are trapped between the wiper blades and the windshield; 2. Poor quality of the wipers. It's important to note that wipers are made of rubber. After driving on rough roads, it's advisable to check the wipers for any debris. If present, it should be cleaned promptly as visibility is crucial for driving safety. In the case of poor-quality wipers, inferior rubber often lacks good durability and can easily harden under prolonged exposure to sunlight. When the wipers operate, it's quite normal for them to produce friction noise. In such cases, using sandpaper to smooth them out is necessary.
The sound of windshield wipers is really annoying. I've encountered it several times since the first day I started driving. Common causes include aging wiper blades, hardened or cracked rubber, which squeak when wiping the glass; sometimes dust, oil film, or small stones accumulate on the glass, causing a gurgling noise when the wipers move; loose wiper arms or incorrect angles can cause bouncing and vibration during operation; and a heavily loaded wiper motor may also produce a humming sound. When dealing with it myself, I first check if the glass is clean and try spraying wiper fluid; if that doesn't work, I replace the wiper blades, which are cheap and easy to install. I change them once before the rainy season to avoid distracting noise while driving. Remember, don't force old wipers to work—if you can't see the road clearly in the rain, it's dangerous. When parking, avoid direct sunlight on the wiper blades to extend their lifespan.
